Fantasy: the Identity of the Sword Immortal Has Been Exposed

The swordsman Lu Xuan returned to the lower realm and lost all his skills, so he re-cultivated the way of swordsmanship. Magical weapons and treasures are all foreign objects, but I only need a sword. Monsters and monsters, kill them all with one sword. The evil heretics can be killed with one sword. Arhat Buddha, kill him with one sword. Daozu Zhenren, kill him with one sword. Etc! My identity as a swordsman seems to have been exposed! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
